Stuck at using sig id 0

I'm trying to get the key of a very simple mono project. It just has a Label with "Godot Test".

Command Line:
gdke.exe .\GodotTest.exe

OutPut:
gamever: 4.2.1.stable.release.mono
injecting dll
waiting until udp is ok
using sig id 0

(I don't have access to my computer now so it isn't exact, but it look like)

Update:

I tried to do with the z421.exe file gived in the source code, and it worked.
Here is the full log of the don't-working:

entry = 0x7ff789bd13d0
gamever = 4.2.1.stable.mono.official.b09f793f5
injecting dll (C:\Users\Paolog\AppData\Local\Temp\gdkeinj.dll)
waiting until udp is ok
using sig id 0

And it get stuck here.

I saw a thing changing between my and z421.exe file: the version.
Mine is 4.2.1.mono, and z421 is 4.2.1.custom_build.

To encrypt the PCK, I enabled PCK encrypt, export pck, disabled pck encrypt and export exe.
Why did I do this? By enabling pck encrypt and exporting exe, the exe won't find the pck.
